pliance. Andthis improvement'has for its object: v

To provide a structural formatlon and association of parts in a glaredimmer or llke attachment for spectacles, embodying the features oflightness, durability and cheapness in manufacture combined with aready, convenient and firmv mounting of the attachment in properrelationy on the lens 0r lens frame'of the spectacles and in a readilydetachable manner, all as will hereinafter more fully appear.

In the accompanying drawing Fig. 1 is a rear elevation of the preferredforni of the invention, with the spectacles to which it is applied shownin dotted lines.

Fig. 2 is a top view with the carrying spectacles shown in dotted lines.

- Fig. 3 is an enlarged section of the attachment on line 3 3 of Fig. 1.

Like reference numerals indicate like parts in the di'erent views.

As shown in the drawing, the dimmer member of the attachment is formedfrom a comparatively thin sheet of material, such as Celluloid, andcomprises a pair of counterpart portions 1 and 2, of any usual formarranged in spaced relation to each other to provide the required nosegap 4. In the preferred construction shown in Fig. 1 the two portions 1,2, are integrally connected together by a central connecting portion 3;it 1s however within the scope of the invention to dispense with thisconnecting portion and form the portions 1, 2, as separate units.

In either case each portion 1 and 2 will be formed'with a straightmarginal edge fory substantial attachment in an associated holder orbase member 5 of a detail Aconstruction now to be described.

The holder 5 is formed from a strip of metal folded upon itself in theform of 'a flattened'return bend so as to provide a narrow channel forthe reception of the above 1932. vserial No. 607,563.

mentioned straight marginal edges of the dimmer sections 1 and 2, whichare fixed therein by rivets or other usual fastening means. Midway thetransverse extent of the holder 5 the same is provided with a pivotsleeve 6 preferably formed by a circular bend in the sheet metal` of theholder. Said pivot sleeve .is adapted to afford pivotal connectionbetween the holder 5 and a resilient attaching member 7, by means ofwhich detachable connection of the attachment to a pair of spectacles,is had in a ready and substantial manner.

In the present improvement the resilient attaching member 7 abovereferred to, isformed of a length of round spring wire bent into an openand approximately oval form,

, the middle portion of which has pivotal engagement in the pivotsleeve`6 of the holder 5 aforesaid, and held from independentlongitudinal shift therein by fixed collars 8 having abutment againstthe respective ends of said pivot sleeve, while the respective curved orhook shaped end portions 9 and 10 of the attaching member are adapted toengage the outer margins of the lens or the lens frames of the pair ofspectacles to which this attachment is applied.

To the above end each hook yshaped side portion 9 and 10 of saidresilient attaching means is provided with a plurality of clip members9', 10 inspaced relation and of an angular formation adapted to lprovideholding recesses to receive and engage the outer portions of thespectacles lens at points above and below the pivotal attachment of the,usual temple rods or bows of the spectacles to'attain a substantial yetreadily detachable connection of the parts. 9g

With such construction, the connection is maintained by the resilientnature of the at- '9.-10, in holding engagement with the lens frame ofthe spectacles. me
